Giving materials for repetition and Child Development in Montessori Education Introduction

How to confirm that the final product is fit for its purpose?

In addition to all the preventive measures outlined in the previous paragraph, buyers also routinely test their products. (This is not written in Brad’s case study, so I am adding to it in a way.)
First, of course, there are safety standards that need to be complied with. That’s a must. For example, see this video about some common toy lab tests.
Some companies try to go further, and it’s great. See how Tesla developed their own tests.
Second, the buyer should also conduct other types of tests on some finished products, as an extra assurance. If there is a doubt about a material’s grade, that can be checked (with chemical and/or physical testing).
Reliability and durability testing is quite important, too. (In a way reliability and safety totally overlap, of course.) See some standard drone testing here. If that drone is to be relied on to deliver critical medicine within a tight time frame, poor durability can lead to safety issues.
And third (it should come first, actually), proper verification and validation of product safety during new product development are extremely important. Most safety issues probably come from poor design.

Does this make sense to you? Are you checking material quality in the same ways outlined by Brad (in his case about steel)? Let me know by leaving a comment, please.

How can I overcome my fear of public speaking?

Answer From Craig N. Sawchuk, Ph.D., L.P.
Fear of public speaking is a common form of anxiety. It can range from slight nervousness to paralyzing fear and panic. Many people with this fear avoid public speaking situations altogether, or they suffer through them with shaking hands and a quavering voice. But with preparation and persistence, you can overcome your fear.
